Replying to [comment:20 karsten]:
> The bad news is that I don't have the time before the dev meeting to run
this analysis, and I can't even say whether the weeks after the dev
meeting will be any better. That's why I
[https://people.torproject.org/~karsten/volatile/merged-2016-02-01.csv.xz
uploaded the data] for somebody else to do the analysis and publish
results here. Any takers?
Here is my try: attachment:ptcc.R.
The blue lines show the lower and upper bounds according to the formulas
in comment:20. The heavy gray lines go from 0 to the total number of
responses for the transport across all bridges.
== obfs3 ==
The obfs3 graph shows that the ranges can actually be fairly tight.
[[Image(ptcc-obfs3.png)]]
== meek ==
In the meek graph, the ranges are super small (almost too small to see);
in other words we know the number very precisely. That's because all the
existing meek bridges only run meek and nothing else (just a negligible
number of <OR> connections).
[[Image(ptcc-meek.png)]]
== fte ==
Most of the lower bounds for FTE bottom out at 0 because PT + CC < 1.
[[Image(ptcc-fte.png)]]
There are a couple of anomalies if you look at the full graphs, caused by
rows with duplicate fingerprints. There are just a few of them. I didn't
bother to clean them up. For example,
